What is an Amphibious Excavator AKA Water Excavator?
Besides the typical boom/stick/bucket assembly, amphibious excavators include an amphibious undercarriage, sealed pontoons, and a buoyancy tank which allows the excavator to flow on the surface of the waterway. Also included in the design of this excavator are main hydraulic pumps with traveling motors to help propel the excavator through the water. The added features of this excavator type is what allows this machine to be used in the most demanding water environments.
Excavator SHOOTOUT: Standard vs. Amphibious
Although standard excavators and amphibious excavators are very similar in some respects, the amphibious excavator provides a far greater value because they can do many other tasks that standard excavators cannot handle. Both excavator types are great choices for bulk excavation jobs, track operated, and available in many comparable different sizes. Each excavator type runs on two tracks that allow the weight of the excavator to be distributed more evenly which makes them well suited for soft terrain; and both can be fitted with either a standard length boom/stick assembly or long reach for extending further distances.
The difference is that the amphibious excavator can operate in wet environments that are typical of regions where marshlands, rivers, swamps, wetlands, and many other types of waterways are more common. The standard excavator can operate in water up to 3-ft., while the amphibious excavators are ideal for water up to 6-ft. in depth. Amphibious excavators are also better in environments where soft mud is prevalent.
Amphibious excavators are also a better choice when there is a high risk of exposing an underground water source, which can overcome a standard excavator causing it to become submerged and unretrievable. For any environment that involves water, or the potential for water to emerge, the amphibious excavator is the best choice.
What is an Amphibious Excavator Used For?
One of the most popular applications for amphibious excavators is dredging, where sentiment is removed from the bottom of bodies of water where a specific water depth must be maintained to allow the passage of transportation barges, boats and ships. Maintaining the proper depths of a waterway can increase navigation efficiency for water transportation. Dredging can include a pump and cutterhead that is affixed to the end of the stick; this configuration allows for very precise dredging to avoid undue damage to the bottom and shoreline of a waterway. For applications where mass sediment removal is needed a barge can be used to load the sediment for quick transfer to a dewatering or disposal site. Sediment, as it is being removed from the bottom of a waterway, can be pumped with the use of a pipeline directly to a predetermined location for disposal up to thousands of feet away.

Amphibious Excavation Used For Environmental Remediation
The remediation process consists of conducting a Phase-1 Assessment of the situation, which includes sampling the water and soil. Then, depending on the type and severity of the problem, and course of action is chosen to correct the situation and bring the immediate environment back to a natural condition. Quite often, if the damage has occurred to a body of water, or a shoreline dredging is used to collect the affected sediments and materials at the bottom of the waterway. This material is then moved to an area where a process of decontamination is applied to remove the contaminants from the material, or the material is disposed of in a manner where the material does not cause any further contamination of the environment.
Amphibious excavators are used in this dredging process, and with the use of either a bucket or dredge pump attached to the end of the boom/stock assembly, they remove the contaminated materials for relocation. Amphibious excavators are well suited to work in wet and watery environments. Designed with an amphibious undercarriage, they can maneuver through water up to 6-ft. in depth to access the area that requires excavation. With a dredge pump attachment, they can remove the contaminated and polluted sediment and material from a waterway with surgical precision. The cutterhead at the end of the dredge pump, along with a GPS positioning device can ensure only remove the material that must be extracted, avoiding any further damage to the surrounding environment. If the water is also contaminated, dredge pumps are used to pump the water through a filtration process so the water can be decontaminated and returned to the body of water from which it came.
Once the remediation process is complete the environment undergoes a final assessment to ensure that the damage that was initially caused has been remedied and restored to its original state. Without the use of amphibious excavators and the proper dredging attachments, the environmental remediation process would not be possible. Amphibious excavators and dredge pumps are critical components for restoring damaged marsh and wetlands, rivers, harbors, and many other types of waterways to their original condition.
